Compatibility

This release is only compatible with devices that have been updated using these instructions.

If you attempt to use it without having previously updated your device with the above instructions, then you'll most likely brick it!

Upgrade

The upgrade to 22.03.3 can be performed from either the main firmware or the recovery firmware.

Doing it from the main firmware gives you more flexibility:

  • You can easily preserve your changes

While from the recovery firmware:

  • You can only use the CLI
  • You must manually backup and restore your changes
